TAT6254B 低噪声, 高增益 FTTH / RFoG 放大器

The TriQuint TAT6254B FTTP SFU Video Receiver provides a low noise analog interface to CATV receivers and optical triplexers. The TAT6254B is intended for use in single family unit (SFU) analog video fiber to the premise (FTTP) applications. The TAT6254B exhibits low input noise and distortion that provides performance margin critical to meeting stringent FTTP link requirements, particularly those with all QAM channel loading. It runs on a single 12 volt supply, eliminating the need for an extra ONU power supply. The TAT6254B provides automatic gain control (AGC) to maintain a constant +14 dBmV/ch output to ensure consistent video quality and ease of design. The TAT6254B is fabricated using 6-inch GaAs pHEMT technology to optimize performance and cost. The TAT6254B is pin and functionally compatible with the TAT6254C, though it has significantly increased gain and lower noise for all or near-all QAM deployments.
